Dinosaurs
A new study reveals that young sauropods, despite their parents' massive size, were vulnerable prey that sustained Late Jurassic predators. Researchers from UCL analyzed fossils from Colorado's Dry Mesa Quarry to reconstruct the era's food web. This abundance of easy meals may explain why predators like Allosaurus thrived without advanced hunting traits.

A new artificial intelligence application called DinoTracker can analyze photos of fossilized dinosaur tracks to identify the species that made them, matching expert accuracy in many cases. The tool has revealed potential bird-like footprints dating back over 200 million years, challenging ideas about avian evolution. It also provides fresh insights into mysterious tracks from Scotland's Isle of Skye.
A new analysis of a fossil from Montana's Dueling Dinosaurs site has confirmed that Nanotyrannus lancensis was a mature species, not a juvenile Tyrannosaurus rex. This discovery challenges decades of paleontological assumptions about tyrannosaur growth and diversity. Published in Nature, the research reveals greater predator variety in the late Cretaceous period.

A complete dinosaur skeleton has provided strong evidence that fossils long debated as juvenile Tyrannosaurus rex belong to a separate species called Nanotyrannus. Researchers analyzed a specimen from the 'Duelling Dinosaurs' site, confirming it as a fully grown individual distinct from T. rex. The findings challenge decades of palaeontological arguments.
